As I did not get any answer to any of my last questions, I had to figure out the solutions by myself. One problem was about a bug in version 2.0 of Travelia template. So I decided to get rid of it and to modify the website usint the Helix ultimate template. This took me some time, to tweak it in order to get an acceptable look and feel.
Another problem I am still waiting for an answer is about SP Page Builder.
I use SP PageBuilder within Joomla articles, and with version 3.8.9 it's working fine, but is it reasonable to keep an old version when a newer is available.
So I installed the update, and with 4.0.6, it is not working anymore. I get blank pages. This is my last step before going live with the migrated website.
Please let see you are still alive... and provide me with an answer.
Thanks
